The salt PhSCF2CF2SO3Li appears promising for lithium-polymer batteries. Its poly (oxyethylene) complexes, although less conductive than lithium imide complexes, provided cationic transference numbers ranging between 0.45 and 0.5, enabling high cationic conductivities to be obtained. Thanks to its double substitution by aryl and perfluorinated moieties, the thioether function is stable enough to be used with positive electrodes, such as vanadium oxide and perhaps cobalt oxide.
